STM32 MCUs Motor control

Hi there,I am new to motor control and I am trying to set up my P-Nucleo-IHM03 kit with MC Workbench 6.1.2. I would like to use FreeRTOS in combination with the 6-step algorithm but in the "Application Configuration" under "FreeRTOS" it is stated: "Selected hardware boards do not support this feature".I was wondering why FreeRTOS is not supported in this case?With the *same hardware* and the FOC algorithm selected there is no such statement and I am having no issues generating a FreeRTOS project. So for 6-step I would now try to add FreeRTOS in STM32CubeMX, but I would like to know if there is any adamant obstacle that would prevent the combination of 6-step with FreeRTOS either in hardware or the 6-step library?   Thanks     

After following all procedure I am able to generate code, But with some errors. After Loading IOC file in CubeIDE. during build I am Getting this error: stm32g4xx_ll_opamp.h: No such file.MC SDK V 6CubeIDE LatestSelected existing example of B-G431-ESC1, I have this kit and want to control speed of motor using PotentiometerLogs:19:31:14 **** Build of configuration Debug for project ElectronicSpeedControl_ESC-G4 ****make -j4 all arm-none-eabi-gcc "../MotorControl/App/motorcontrol.c" -mcpu=cortex-m4 -std=gnu11 -g3 -DDEBUG -DUSE_HAL_DRIVER -DSTM32G431xx -c -I../MotorControl/App -I../MotorControl -I../Core/Inc -I../Drivers/STM32G4xx_HAL_Driver/Inc -I../Drivers/STM32G4xx_HAL_Driver/Inc/Legacy -I../MCSDK_v6.1.2-Full/MotorControl/MCSDK/MCLib/Any/Inc -I../MCSDK_v6.1.2-Full/MotorControl/MCSDK/MCLib/G4xx/Inc -I../Drivers/CMSIS/Device/ST/STM32G4xx/Include -I../Drivers/CMSIS/Include -Ofast -ffunction-sections -fdata-sections -Wall -fstack-usage -fcyclomatic-complexity -MMD -MP -MF"MotorControl

Hello.I want to use NUCLEO-G491RE with MCSDK6.1.2. However, NUCLEO-G491RE does not exist in the list of "Control" of MCSDK. If I have a NUCLEO-G491RE JSON file, can I import it? Where can I get the JSON file?Thank you.

Hello,I'm following this tutorial to see what functions I can use to control the motor I'm using : STM32MotorControl:6-step Firmware Algorithm - stm32mcu (stmicroelectronics.cn)Based on that the functions presented there are just the main ones, the complete definition is available in the STM32 MC SDK Reference Manual but I can't find it. Can someone point me to the API documentation? 

I install different versions of CubeMX, CubeIDE on Windows10 and Linux with MCSDK MCMonitor and Trying and trying to make it work but end up with only errors. I feel to make it more simple software become un usable. And there is no integrity between versions. I don't find my board in Latest CubeIDE i.e B-G431B-ESC1 board. Simple things work much better. Unable to connect with server. On every step there is error.

Hello!I'm working on a prototype using FOC, and I got everything working with the following scheme:NUCLEO-F401RE, Custom Power Board, CubeIDE 1.12.1, CubeMX 6.8.0, Motor Pilot 1.1.12 and MCSDK 6.1.2.Now I'm trying to do the same thing but with the STM32F401CCU6 (48-UQFPN). I'm importing the first project that works, but in order to import the same project I need to relocate the current sensing pins, since on the Nucleo they are on PortC (that are not present on the 48-pin MCU). I couldn't find a straightforward way to do this, and just relocating the pins in CubeMX isn't working (even though I'm making sure everything has exactly the same configuration as before).I've already looked a lot in the official documentation of this version of the SDK about pin reallocation, and I wasn't successful.Any kind of help would be appreciated! Thanks 

I bought the assembly B-G431B-ESC1 to test BLDC motor. I have already installed the software SDK V5.4.8, StmCubeMX and StmCubeID 1.13.0. Unfortunately, when generating the code, there are various errors that I can't figure out. Also, how can I load the finished software via stmCubeID. the board has an embedded ST-link. the stmCubeID does not recognize the driver. how can still access the board. Thank you guys for the support   

There is mistake in either the documentation or the source code, which one is correct please advise. __weak uint16_t PWMC_SetPhaseVoltage(PWMC_Handle_t *pHandle, alphabeta_t Valfa_beta) { wUAlpha = Valfa_beta.alpha * (int32_t)pHandle->hT_Sqrt3;  wUBeta = -(Valfa_beta.beta * ((int32_t)pHandle->PWMperiod)) * 2; }   But if you compare with the documentation In the alpha code the PWM period (T) is missing. In the beta code additional 2 is found. Why there is a difference? Please help.

I have PM-SMPSM motor that I'm trying to get to spin with the STSPIN3201 - I seem to be able to configure the project in the MC workbench, generate code, and load it onto the micro through CubeIDE just fine - but no matter what I do, the motor moves slightly when I try to spin it up, and the rotor locks in a fixed position.  More specifically, it seems to on first boot do a search to determine the encoder/winding relationship by doing a short ramp, but then it does the rotor lock every time I request a speed.  The rotor isn't locking in a fixed position, but it seems to be cogging to one of several fixed positions and locking there.  Things I have tried:I have confirmed that the encoder is working by spinning the motor manually and watching the speed, plotted by motor pilotI have changed the phase winding order of the motor, trying each possible phase wiring in turn, just to make sure it's not just commutating incorrectlyI've plotted current on the scope, it looks ok in

I have a custom board based upon the B-G431B-ESC1. Using the LQFP48 foot print version of the same chip. It is missing a few pins, but my project is not using them.After creating a new project using STM32G431CBT6 and the importing the original from MC workbench, I have 2 faults showing on CubeMX.ADC1 and ADC2 Clock Prescaler cannot use clock div1I choose div4 as I can't see anything in the data sheets to exclude div1 and MX proceeds to generate the code. After loading the project into CubeIDE, I change the div4 to div1 and all compiles fine.Why does Cube MX create these errors? Is there an incompatibility?Thank you for any insight into this.Kind Regards.P

I was looking at the datasheet for the VNH5019, and saw that the current sense gain tolerance is narrower as it drives higher currents. I am trying to use the driver in an application where the motor currents can range from about 100mA to 10 A, and am hoping to gain some insight on the tolerance range for the current sense in the 0 - 1000mA range, since I have seen a very wide range of errors in the current sense calculation (up to 100%, with outliers even worse than that). 

Hi,I am using STSPIN32F0601 eval board in sensorless configuration with RSHUNT for current measurement. The issue is that the measured motor power from function PQD_CalcElMotorPower is incorrect. It has an offset with respect to the actual motor power and this error varies with respect to change in RPM.  Although the relationship between RPM and this offset is not linear, it is observed that the offset is higher in higher RPMs and reduces towards lower RPMs. What could be the cause of this issue?Secondly, I have custom made prototype boards for my application, where I have followed recommended circuit as per the documentation and eval board. In those PCBs I have found that this measured power offset is not consistent across all PCBs. The error band is different in 3 out of 10 PCBs. What is causing this variation? What points should I look for in these PCBs to differentiate the factor causing this variation?How can I get correct motor power where in atleast the error offs

My group in university got the L9907 Eval board to drive a BLDC motor. All jumpers on that board are set with default option. We have the problem, that the L9907 does not work as expected. The outputs of GHS_1, GLS_1, GHS_2, GLS_2, GHS_3, GLS_3 are all 0V. But we connect a pwm signal to PWM_H1 and PWM_L3 and enabled both EN pins (EN1, EN2). Furthermore the boost circuit is not 10V higher then the consumption. Is there any more step to do before this chip works?Thank you in advanceMore info: BST_DIS connected to PGND. VBAT=12V on both boards

Hello, so this is how I decided that I wanted to create a CNC machine for plasma cutting and also an option for milling*The machine will work on 5 axesAnd of course I also have a software code that has already been created that will run the engines for me with the shifts etc...*Motor drivesI purchased 6 PCB boards of the STEVAL-SPIN3204 type, from STMicroelectronicsI use powerful brushless motors that I haveOnly the boards I mentioned match the Volt and Amps of the motors I have*MicrocontrollerSo that I can run 6 motors at the same time in different directions and speedsI will have to connect the motor drives to a microcontroller that knows how to synchronize the software with the motorsAnd here I encountered a small problem that I am trying to figure out how to connect the motor drives to the STM32 Nucleo 144 microcontrollerI would appreciate some help for this thank you very much!

Hi,when generating code with Motor Control Workbench for the B-G431B-ESC1 there is no code generated for CAN or PWM. Pin assignment in CubeMX is also missing.Is the B-G431B-ESC1 not supported in Motor Control Workbench, yet?Kind Regards,Jay

I have generated a Motor Control solution for CubeMX using MC Motor Workbench 5.4.4 and NUCLEO-G431RB and NUCLEO-IHM08M1 and successfully tested with my motor.How can I to migrate the CubeMX project (*.ioc file) to a different MCU (STM32G431V(6-8-B)TX)?

I would like know if STM32G0C1VE meets the AEC Q100 qualification for automotive applications. 

I am using a B-G431B-ESC1 inverter board to run a 36v 10A hub motor. The board is based on the STM32G431CB microcontroller so I am using the STM motor control environment to generate code for this project. Their Motor Control Workbench has a motor profiling program to get the specs from a custom motor like the one I am using. From this motor profile, along with many other parameters, STM32CubeMX generates code for the B-G431B-ESC1. We then upload this code through the STM32cubeIDE and try to run the motor with the ST motor pilot. The problem is the code never seems to work right. The motor doesn’t run and returns one of a few errors depending on the parameters we set up in the Motor control workbench. Is there some parameter we are missing that is important for this board? Since we are staying within the STM environment it doesn’t make sense that the generated code keeps failing. It’d be great to get a response soon as I am trying to figure this out in the next week. I can provide more

I'm trying to generate the firmware for my B-G431B-ESC1 but it doesn't compile in CubeIDE.Previously I was using the 5.4 version, but I decided to update to 6.1.2 since I saw that it had a better firmware generation. However, There are a lot of errors that seem like a variable has been renamed, for example:../MCSDK_v6.1.2-Full/MotorControl/MCSDK/MCLib/G4xx/Src/r3_3_g4xx_pwm_curr_fdbk.c:1425:28: error: 'PWMC_Handle_t' {aka 'struct PWMC_Handle'} has no member named 'bMotor'; did you mean 'Motor'?I have generated all of the files from scratch and only changed the main.c/.h files, so It shouldn't influence on this.

I need some advice on the hardware design of the B-G431B-ESC1, i have built custom board with different ratings but based on the schematic provided. My main worry and want to understand is there is some filtering section missing for example Anti aliasing filtering etc for the current sensing. So, can you please comment that the hardware design by ST is perfect and no changes required. I am bit confused. This will help to be more clear and confident.@Gael A 

Hello,I have built an ESC based on STSPIN32G4 and created a software for it using MC SDK. I did select the following in MC Workbench: Inverter, EVSPIN32G4. Did not change any other options. Schematic of my PCB is based on the EVSPIN32G4 electronic with 1-to-1 pinout.Behaviour when I power-on my board:There is no communication over USART.MC_MotorControl_Init() never returns.HAL_Delay() works twice slower as expected - HAL_Delay(500) takes one second.Of course, due to the listed problems, motor control does not work.I am still able to flash any other of my demo software on this board and it works (triggering GPIOs, communicating over USART and I2C) but I am still not able to let the "original" software generated by MCSDK to run.Does anyone has an experience with this issue? Do I need to set some specific options in MCSDK to let software run on STSPIN32G4?On the picture you can see the ESC part of my board.Thank you in advance.

I designed my own PCB largely based on the EVALSTSPIN32G4, mine being a four layer board with components on both sides for compactness.I generated code using MC Workbench 5.Y.4 with hall sensors. I implemented my own absolute encoder via SPI, and added CAN Bus communication.Everything seems to be working fine, except that the MCU seems to be running at 60 to 70 degrees Celsius, and the board will eventually stop working.I am powering it with a 22.2V 6 cell LiPo battery, but I have also powered it wit ha proper power source. Running firmware for motor control only, with motor idle, the board pulls 0.15A at 24V. With the motor running it pulls 0.3A. Adding the encoder or CAN Bus does not add any significant current draw.The only caveat is that I am bypassing Boot0 on pin B8 by clearing nSWBOOT0 on flash, since I use that pin for one of the hall effect sensors.Below is the current NVIC table. I am using an interrupt for the encoder over SPI, but I might change that to DMA if it helps.So t

 Hi guys, I'm working on an EV motor control project, the motor type is IPMSM, and on it’s Drive, I have found that it measures the motor voltage feedbacks (middle point of inverter legs) by Op-amps (inverting Configuration) -> MCU input.The inverter is two-level, so we have a PWM-type waveform.The control system uses these measurements directly on its algorithm; switching got disturbed after cutting one of the op-amps inputs off. And motor stops.My question is that what is the application of those measurements? Does anyone have a similar experience? Industrial Drives doesn’t include this section; so, I think it’s specifically for EV traction applications.This Drive uses a single shunt current sensing method + Hall position sensor for closed loop.The circuit schematics and output waveforms are attached.

Good day!Please tell me where I could see the connection diagram for controlling two brushless motors using STSPIN32G4? I couldn't find any information on the site. I saw a video on youtube https://www.youtube.com/watch?v=E8NkogGR--s But i couldn't find info and schematics or developer board for two BLDC motors Thank you!
